To all whom 'it may concern.

Beit known that I, EDWIN zen of the United States, residing at New Orleans in the parish of Orleans and State of Lou1s1ana,'have invented certain new anduseful Improvements in Methods of Attaching Teeth to Dental Plates; and I do here-. by declare the followin to be a full, clear, and exact description of the. invention, such as will enable others skilled in the art to which it appertains to make and use the same. I My present invention relates to an improved method of constructing artificial dental plates.

' In my former applications entitled dental plates and methods of manufacturing same, Serial N0.423,341, filed March 26, 1908, and dental plates, Serial N 0. 440,187, filed J une 24, 1908, I have described a method and its plate and the socket of product whereinthe the tooth segment were both'rnade of some suitable material, such as celluloid, the surmight be dissolvedby the abutting surfaces together; but a great many plates are already in use, and many others are likely to be used hereafter, in which vulcanite or other material is used which is notsoluble for the purposes stated, my present invention is intended to carry forward the process described in my two prior applications above referred to, so that single teeth or segments containing a plurality of teeth may be added to such plates already constructed, tov growing needs of the'wearer; or that teeth broken from such plates may be replaced; or

a suitable solvent and that an artificial tooth too'low may be raised,

or one too high may be lowered; or that artificial teeth out of position may .be changed; or objectionable artificial teeth may be replaced by others more suitable, with out necessitating the construction. of an entirely new plate.

Where there is a missing tooth or'teeth on a rubber plate the same may be added in a most novel manner by excavating the plate or creating a receptacle at suitable spaces where the tooth is to be added, these excavations or retaining points to be filled with powdered celluloid or celluloid filings.

Large numbers of sets of teeth on rubber, and other materials, now worn, are loose,

By nidof my pre wabbly sets may be TE'LLE, .a citi-' supply the made satisfactory to an extent, heretofore unknown in this field of dentistry, Clasps when required. To illustratefon a loose plate, adjust a sufficient quantity of impression compound while the plate is held securely in the mouth.- With fingers press the warmed compound to surface. Same pro: ceeding .for other side of plate when required. 1 Embed the prepared plate 1n plaster, remove the compound. If it 1s a rubber plate excavate and pack with celluloid, as already described. For gold plates,

alter so as to give stability, the rest, sameas for rubber. Note that the segment principle maybe readily applied to all bases,

solventether and alcohol-4s gradually apsolvent, packing it in until a proper height. has been obtained. These receptacles and retaining points are filled gradually, partially filling each retaining point with powdered celluloid, then using the solvent and a heated instrument to condense the celluloid and disperse the solvent, the work is done slowly. add the powder slowly, then the sol.- vent and then the heated instrument is used, notso hot as to blister the plate, and so on until the proper height is obtained.

Proceeding with the tooth, it may be waxed up, flasked, and pressed in the usual way, after which adjust to position and complete packing, take the powder and press it around the pins therein contained, touch with the solution and proceed as above described, thenadjust the tooth to its proper position. It might be embedded in plaster, but this is not always essential, first adding to adhere 'to the celluloid surface above'described, it becomes firm in a few moments which is hastened by heat as above described To add segmentsto rubber plates, excavate undercut pits, points both in the plates and in the segments, fill th'ese excavations with celluloid fillings and solid bits of celluloid, dissolve til firmly set. Heatingslightly will facilita'te the process. In a similar way teeth broken from such others.

When it is desired to raise a tooth already on the plate,

where segments are to rest, cut, bend and plied, adding more celluloid and more of the the solvent solution which causes the tooth or slots at proper plates are replaced by cut the tooth segment from of-celluloid or gold may be readily added After packing in the c ielluloid, a proper 105. the celluloid on each, and press together unthe plate, and build up with celluloi d be- I tween the cleavage surfaces, and unite the parts by a; solvent as hereinbefore described.

v To lower a tooth, cut the tooth segment from the plate and cut away some of the material, and then unite the cleavage surfaces ashereinbefore described. In a similar'Way artificial teeth out of position may be adjusted, or objectionable teeth removed "and others added.

ments carrying a plurality of teeth, may be applied in the method hereinbefore' described to various kinds of plates now in use other than vulcanite plates.

Having thus described my invent-ion, what I claim and desire to secure-by Letters Patent of the United States is 1. The method of attaching artificial teeth to plates of vulcanite or otherordinarily insoluble material, which consists in forming a recess in the plate, filling-this recess with soluble material, applying similar material It will be obvious that single teeth, or seg- 'abutting'lfaces of said." material with any suitable vaporizable solvent, and forming a.

weld by pressing said dissolved faces to- 55' gether, and applying heat to-the joint, substantially' as described.

2. 'The method of attaching artificial teeth to plates of vulcanite orotherordinarilyin soluble material which consists informing a recess in the plate, filling this recess with;

powdered celluloid, dissolving'this celluloid with any suitable vaporizable solvent such as alcohol and ether, applying partially dissolved-celluloid to the abutting face of the tooth or tooth segment, dissolving the abut:
